The Adelaide Driving Self-Efficacy Scale (ADSES) is a reliable and valid tool for measuring driving confidence in stroke survivors and the general population. It accurately assesses self-efficacy related to driving behaviors.
Area of Science:
- Rehabilitation science
- Clinical psychology
- Neuroscience
Background:
- Driving cessation significantly impacts independence and quality of life for individuals post-stroke.
- Accurate assessment of driving self-efficacy is crucial for rehabilitation planning and return-to-driving decisions.
Purpose of the Study:
- To develop and validate the Adelaide Driving Self-Efficacy Scale (ADSES).
- To establish the reliability and validity of the ADSES in assessing driving self-efficacy.
Main Methods:
- The ADSES was developed based on literature review, clinical expertise, and expert consensus.
- Internal consistency was assessed using Cronbach's alpha; construct validity by comparing stroke and non-stroke drivers; criterion validity against standardized on-road assessments.
- Participants included stroke patients and non-stroke drivers from a rehabilitation hospital setting.
Main Results:
- The ADSES demonstrated high internal consistency (Cronbach's alpha = 0.98).
- Significant differences in ADSES scores between stroke and non-stroke groups confirmed construct validity.
- ADSES scores significantly differentiated between participants who passed and failed on-road driving assessments, confirming criterion validity.
Conclusions:
- The ADSES is a reliable and valid measure of driving self-efficacy for both stroke survivors and the general population.
- The scale effectively correlates with objective on-road driving performance.
- The ADSES can be a valuable tool in clinical practice for evaluating driving confidence.
